Calculating mmol From Grams of Substance If you have 0.33 grams of sodium chloride (NaCl), how many mols is that? How many mmols? To find the molar mass of sodium chloride, you first go to the periodic table. Underneath the element symbol, you will find the molar mass. For sodium, it...
Molar Mass of H:1.01 g/mol ElementSymbolAtomsMass % HydrogenH1100.0% Observe the numbers that are written in a reaction equation. For instance, you may have a combination of carbon dioxide and water as such: (3)CO2 + (4)H2O Notice the three and the four, which indicate the numbers of...
simply add the individual masses of the atoms, being sure to account for subscripts. So for a water molecule, H2O, you would add the mass of 1 mol O (15.999 g) to the mass of 2 mol H (2 × 1.008 g, or 2.016 g) to get about 18.015 g. ...

Titration is a process for finding the concentration of a chemical solution. Titration makes use of the physical evidence of a chemical reaction to determine the amount of a known chemical that is required to completely react with the unknown chemical. T
